A CONVICTED dealer ran a £500,000 Europe-wide drugs ring while behind bars.

Paul Bulman directed the lucrative operation using hidden mobile phones from his prison cell at HMP Edinburgh.

The 26-year-old, of Knightswood, Glasgow, is back in prison after he admitted being concerned in the supply of pentedrone.

Bulman faces a lengthy jail-term when he returns to the High Court in Glasgow next month for sentencing.
